Mystery catalog numbers

 I have found some of my grandpa's Montgomery Ward receipts from 1950. They don't say what he bought or what specific catalog or exact year it was, just a catalog number. 

Is there anyone on the internet who can show me a site with all the catalog numbers, or do I have to buy all the catalogs from 1950 to find out? Surely someone has a catalog and can leave a message here saying that grandpa ordered some socks and a belt, right? Seriously, that's just a guess, I don't know what any of these catalog numbers mean. Any ideas? Or will I never find out what these are?

Catalog numbers:

MA4609,

45AP5603 (costs $2.34),

53A1626 ("Ames let dev ns" for $79? $7.90?),

53AP5325 (quantity 1, "ton ns" for $95? $9.50?),

30A278 (quantity 3, "gy 11" for $115? $1.15?),

45A5583 (quantity 2, "bra loc" $9.95. okay, so this might have been something grandma ordered, but I have no idea about the other items listed above)

I guess I'll never know.
